rudelude whats your setup? Yeah going from a .42/.48 to a T3/T4 is going from somthing thatll support 250hp barely to somthing that supports 400+ you should notice a little power gain at least because of the less restrictive compressor... does it spool later and/or act more laggy?

Edit: I was looking at the compressor maps between the t3 and 50 trim T04E (looks like T04E) and the T4 compressor has a few percent increase in top efficiency over the t3 (unbeknownst to me)

 

spool is still the same. Just alot more power up top and just a smoother overall powerband.

.42/.50, T3/T4, FMIC, RC 550, Uberdata, Tial 38mm WG, HKS SSWV BOV, Custom built mani, muston DP, Custon made Charge Pipes, Tunertoys Oil kit.. Prolly more stuff im forgetting.

 

Wholly moley! that mani looks like it was made with old sewer piping or something! badass

 

i dont get it wut is the diff from a t3 t4 aight they the same turbo

 

T4 comp housing and wheel, with a T3 exhaust and wheel. Same spool more topend.

 

lol
